Filed:

Jan 30, 2007

Appl. No.:

11/699949

Inventors:

Ray D. Kanter - Dallas TX, US
Morgan L. Crow - Ovilla TX, US

International Classification:

E04F 15/22

US Classification:

524031, 5274519

Abstract:

The present invention provides a cushioned impervious flooring usually formed in place. At least one layer of closed cell cushion is overlaid with a reinforcing mesh having interstitial spaces, a layer of adhesive is applied to adhere the reinforcing mesh to the cushion and to adhere the reinforcing layer to a layer of sheet flooring. Tapered edges provide gentle transition from the cushioned impervious flooring to adjacent surfaces at a different elevation. Joints in the closed cell cushion, reinforcing layer and sheet flooring are offset from each other to provide smooth installation and more strength.

International Classification:

E21B 43/12
E21B 4/04
E21B 17/00

US Classification:

166 664, 1662426, 166 651

Abstract:

The invention relates generally to oil and gas exploration and production and, more particularly, to a system and associated method for producing hydrocarbons from multiple layers of subterranean formations, and the mixing or comingling of such hydrocarbons as necessary or desired during the production process. A subterranean tool is disclosed, having a plurality of tubular sections connected by a novel non-threaded linear connection system. An electrical passage can then be provided within the cylinder wall of contiguous sections permitting connection of electronics in different sections of the tool. Bushings and seals located in the electrical passage maintain an atmospheric pressure environment for electrical components inside the tool.

International Classification:

E21B 17/02

US Classification:

175 45, 1662426

Abstract:

An adjustable bent drilling tool capable of changing in situ drilling direction to facilitate horizontal drilling. The drilling tool may be controlled from the surface and eliminates the need to bring the tool to the surface for reconfiguration. In one embodiment, the drilling tool utilizes a communications module to communicate with upstream sections of the tool. The communications module is connected to a programmable electronic control module which controls an electric motor. A hydraulic valve assembly follows the control module, which receives input signals and controls a pilot piston between two fixed points of a mid-assembly typically located adjacent to and downstream of the hydraulic valve assembly on the drill tool. A lower assembly is attached to the drill tool immediately following the mid-assembly, and provides both a safety release sub-assembly as well as a bendable sub-assembly which directs the adjustable drill tool to change drilling angle and direction.

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 31113

US Classification:

175297

Abstract:

A hydraulic jarring tool for imparting up-jarring impacts to release a stuck earth boring drill string component is shown. The tool defines upper and lower closed fluid chambers between telescopically moveable concentric cylinders. A fluid metering valve in one fluid passage between the chambers provides limited flow from one chamber to the other and permits telescopic movement at a rate which establishes tension on the drill string and causes the tool to jar. A normally open valve is provided in a by-pass passage between the chambers and is responsive to the fluid velocity therethrough to move to a closed position, restricting fluid flow to pass through the metering valve. However, the tool can be telescopically extended at a somewhat lesser rate insufficient to cause the velocity responsive valve to close thereby permitting the tool to be extended smoothly without a jarring impact.

Appl. No.:

6/075282

Inventors:

Morgan L. Crow - Dallas TX

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

F16C 2100

US Classification:

308 82

Abstract:

A sealing system provides a metal-to-metal barrier to the drilling fluid, pulverized cuttings and other materials in the borehole preventing the materials from entering the bearing area of an earth boring bit and a positive elastomer seal retains lubricant inside the bearing area. The body of the bit includes a bearing pin and a rolling cone cutter is mounted to rotate about the bearing pin. A sealing surface is provided on the bit body. An annular metal seal ring is positioned around the bearing pin adjacent the sealing surface. An elastomeric ring is positioned around the bearing pin and compressed or deformed axially to urge the metal seal ring into sealing engagement with the sealing surface. A lip projects from the elastomeric ring and contacts the sealing surface to provide a positive initial seal for filling and testing.

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 702
E21B 704

US Classification:

173 2

Abstract:

An automatic alignment control system for an earth boring rig utilizes sensor means on the drilling mast for actuating switches connected to power controls. The sensor means reacts to misalignment of the drilling mast vertical axes to close appropriate switches which in turn generate signals to power means which are arranged to shift the mast axes in the appropriate direction for proper vertical alignment.

Appl. No.:

6/082386

Inventors:

Morgan L. Crow - Dallas TX

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

E21B 1052

US Classification:

175374

Abstract:

One or more holes are drilled into the crest of the tooth-shaped cutting structure of a milled steel tooth rotary rock bit. Tungsten carbide rods are positioned in the holes and hardfacing is applied to the tooth. The hardfacing is applied across the top of the tooth crest and acts to hold the tungsten carbide rods in place. The rods are inserted in holes parallel and close to one flank of the tooth so that the entire length of the carbide rods can be attached to the hardfacing by burning the hardfacing through to the carbide rods. Wear on the tooth will proceed along the side of the tooth not reinforced with the carbide rods and a self-sharpening effect is enhanced by the strength of the carbide rods. The carbide rods and holes therefore can be relatively inexpensive, since close tolerance finishing is not required.

Assignee:

Dresser Industries, Inc. - Dallas TX

International Classification:

G01C 1500

US Classification:

33286

Abstract:

Methods and apparatus for vertical alignment of a borehole rig directly over a drilling site involve use of a camera placed in parallel orientation to the drilling mast or drill string and sighted in on the drill target, then allowed to swing free to the true-plumb position, thereafter bringing the mast back into parallel orientation with the now-plumb camera.
